PNNL researchers are examining the volatile radioisotope iodine as it evolves in the atmosphere and as it lands on a filtering surface. A more detailed understanding of the interactions and chemical evolution of radioiodine could help first responders’ decision-making after the release of volatile iodine into the environment, which happened following nuclear power plant accidents in 1986 at Chernobyl and in 2011 at Fukushima.
Nuclear bomb tests during the Cold War in the 1950s and 1960s have helped scientists accurately estimate the age of whale sharks, the biggest fish in the seas, according to a Rutgers-led study. It’s the first time the age of this majestic species has been verified. One whale shark was an estimated 50 years old when it died, making it the oldest known of its kind. Another shark was an estimated 35 years old.
Tadpoles can be used to measure the amount of radiocesium, a radioactive material, in aquatic environments, according to new research from University of Georgia scientists. Whether from nuclear accidents, global fallout from weapons testing, or production of nuclear energy, tadpoles…
